[RFC PATCH v2] Add ARM cpu topology definition

2011-06-20 Thread Vincent Guittot
The affinity between ARM processors is defined in the MPIDR register. We can identify which processors are in the same cluster, and which ones have performance interdependency.We can define the cpu topology of ARM platform, which is used by sched_mc and sched_smt. The default state of sched_mc and
